shenleiandClaude Opus 5 5fad769ee8 port 2P step 1: vendor CPython 2.7.18 as the mtpython static library 
The embedded 40250 script layer needs its own interpreter on five platforms.
2.7 is end-of-life, so nothing can be fetched from the target SDKs and the
source is vendored (official 2.7.18 tarball, trimmed to 25MB; Lib/ stays for
step 3's python27.zip).

cpython-2.7.18/CMakeLists.txt builds one `mtpython` static library from exactly
the 133 objects the reference libpython2.7.a contains, off by default behind
-DMTGODOT_EMBED_PYTHON=ON. The source list and the built-in module table
(config/config.c, 39 entries) are shared; pyconfig.h is a probe result and is
not, so each platform keeps its own under config/<platform>/, regenerated by
tools/py_embed/gen_pyconfig.sh and checked against the shared table.

Three vendor patches, documented in docs/THIRD-PARTY.md: configure/configure.ac
learn arm64 on macOS, and posixmodule.c undefines the process-control calls it
hard-defines past pyconfig.h when building for iOS.

macOS (ctest python.embed: every builtin imports, codecs and pickle work off the
vendored Lib/), Android arm64 and iOS arm64 build. Linux needs a Linux host and
Windows needs a MinGW-vs-MSVC decision; both are noted for step 4.

/* ------------------------------------------------------------------------
_codecs -- Provides access to the codec registry and the builtin
codecs.
This module should never be imported directly. The standard library
module "codecs" wraps this builtin module for use within Python.
The codec registry is accessible via:
register(search_function) -> None
lookup(encoding) -> CodecInfo object
The builtin Unicode codecs use the following interface:
<encoding>_encode(Unicode_object[,errors='strict']) ->
(string object, bytes consumed)
<encoding>_decode(char_buffer_obj[,errors='strict']) ->
(Unicode object, bytes consumed)
<encoding>_encode() interfaces also accept non-Unicode object as
input. The objects are then converted to Unicode using
PyUnicode_FromObject() prior to applying the conversion.
These <encoding>s are available: utf_8, unicode_escape,
raw_unicode_escape, unicode_internal, latin_1, ascii (7-bit),
mbcs (on win32).
